The load cell (1) has a deformation body (2) with an upper contact surface (3) and a lower contact surface (4). The contact surfaces (3, 4) are designed for introducing force into the deformation body (2) and each have a support point (5), wherein the current support points together form a force reference line (6). A columnar region (7) of the deformation body, having a central longitudinal axis (8) and an outer surface line parallel thereto, is arranged between the contact surfaces (3, 4). The load cell (1) further comprises a first determination means (9), which is mounted on the columnar region (7) of the deformation body (2) and converts the mechanical deformation of the deformation body (2) into a signal, and a second determination means (10), which is mounted on the columnar region (7) of the deformation body (2) and converts a deviation of the central longitudinal axis (8) from the force reference line (6) into a signal. The first determination means (9) and the second determination means (10) each have at least one strain sensor. The at least one strain sensor of the second determination means (10) is mounted substantially centrally between the upper contact surface (3) and the lower contact surface (4) and is oriented by a predefined acute angle relative to the outer surface line in such a manner that the signal of the second determination means (10) becomes null if the central longitudinal axis (8) does not deviate from the force reference line (6). |
